Sheet post-processing device, and image forming apparatus including sheet post-processing device

Abstract

A sheet post-processing apparatus according to one aspect of the present disclosure includes a switching member, a stapler, and a movement driving portion. The switching member switches the conveying direction of a sheet introduced from an image forming apparatus. The stapler staples a bundle of sheets obtained by performing stacking processing for a plurality of the sheets introduced from the image forming apparatus. The movement driving portion moves the stapler. Further, the stapler operates the switching member by being moved by the movement driving portion, thereby switching the conveying direction of the sheet.

The invention claimed is: 
     
       1. A sheet post-processing apparatus comprising:
 a switching member that switches the conveying direction of a sheet introduced from an image forming apparatus; 
 a stapler that staples a bundle of sheets obtained by performing stacking processing for a plurality of the sheets introduced from the image forming apparatus; and 
 a movement driving portion that moves the stapler, 
 wherein the stapler operates the switching member by being moved by the movement driving portion, thereby switching the conveying direction of the sheet. 
 
     
     
       2. The sheet post-processing apparatus according to  claim 1 , wherein
 the stapler is capable of executing end stapling processing of stapling the vicinity of a corner of the sheet, and two-point stapling processing of stapling two portions along an edge of the sheet, and 
 the stapler operates the switching member at an operation position defined between a first position for executing the end stapling processing and one of second positions for executing the two-point stapling processing, that is closer to the first position. 
 
     
     
       3. The sheet post-processing apparatus according to  claim 2 , wherein when the stapler operates the switching member, the switching member switches the conveying direction of the sheet so as to convey the sheet to a processing portion that mainly performs processing other than stapling processing of stapling the sheet by the stapler. 
     
     
       4. The sheet post-processing apparatus according to  claim 3 , wherein a mechanism that operates the switching member is provided outside a region where the sheet is conveyed. 
     
     
       5. The sheet post-processing apparatus according to  claim 2 , wherein a mechanism that operates the switching member is provided outside a region where the sheet is conveyed. 
     
     
       6. The sheet post-processing apparatus according to  claim 1 , wherein when the stapler operates the switching member, the switching member switches the conveying direction of the sheet so as to convey the sheet to a processing portion that mainly performs processing other than stapling processing of stapling the sheet by the stapler. 
     
     
       7. The sheet post-processing apparatus according to  claim 6 , wherein a mechanism that operates the switching member is provided outside a region where the sheet is conveyed. 
     
     
       8. The sheet post-processing apparatus according to  claim 1 , wherein a mechanism that operates the switching member is provided outside a region where the sheet is conveyed. 
     
     
       9. An image forming apparatus comprising:
 an image forming apparatus main body having an image forming portion that forms an image on a sheet; and 
 a sheet post-processing apparatus, wherein 
 the sheet post-processing apparatus includes:
 a switching member that switches the conveying direction of the sheet introduced from the image forming apparatus; 
 a stapler that staples a bundle of the sheets obtained by performing stacking processing for a plurality of the sheets introduced from the image forming apparatus; and 
 a movement driving portion that moves the stapler, and 
 
 the stapler operates the switching member by being moved by the movement driving portion, thereby switching the conveying direction of the sheet. 
 
     
     
       10. The image forming apparatus according to  claim 9 , wherein
 the stapler is capable of executing end stapling processing of stapling the vicinity of a corner of the sheet, and two-point stapling processing of stapling two portions along an edge of the sheet, and 
 the stapler operates the switching member at an operation position between a first position for executing the end stapling processing and one of second positions for executing the two-point stapling processing, that is closer to the first position. 
 
     
     
       11. The image forming apparatus according to  claim 10 , wherein when the stapler operates the switching member, the switching member switches the conveying direction of the sheet so as to convey the sheet to a processing portion that mainly performs processing other than stapling processing of stapling the sheet by the stapler. 
     
     
       12. The image forming apparatus according to  claim 11 , wherein a mechanism that operates the switching member is provided outside a region where the sheet is conveyed. 
     
     
       13. The image forming apparatus according to  claim 10 , wherein a mechanism that operates the switching member is provided outside a region where the sheet is conveyed. 
     
     
       14. The image forming apparatus according to  claim 9 , wherein when the stapler operates the switching member, the switching member switches the conveying direction of the sheet so as to convey the sheet to a processing portion that mainly performs processing other than stapling processing of stapling the sheet by the stapler. 
     
     
       15. The image forming apparatus according to  claim 14 , wherein a mechanism that operates the switching member is provided outside a region where the sheet is conveyed. 
     
     
       16. The image forming apparatus according to  claim 9 , wherein a mechanism that operates the switching member is provided outside a region where the sheet is conveyed.
